ROLLEB-BEARENG.

Application filed July :2,

To all 'LU/"rom t 'moy conce/rn:

Be it known that Financieren lV. Gna- Nuy. a citizen ot the UnitedStates, residing at Jamestown, in theeounty ot' Chautampia and State o tNew York, have invented a new and useful improvement in Roller-Bearings7of which the following is a specification.

This invention relates'to ball or roller bearings ot the imitar)r typein which the halls or rolling elements are arranged to roll in `races orgrooves formed in inner and outer race rings or members. These bearingsimiall'jvr include also a separator or spacer for holding the balls orrolling elements spaced apart,A or at regular intervals in the rares.

'(fne object ot the invention is to produce a bearingl which can beassembled with a full set ol balls arranged in close relationship indeep race grooves so that the bearing is suitable tor taking not onlyradial loads but also Very heavy thrust loads in both directions. Otherobjects ot the invention are to produce a bearing in which one ot' therace rings or members7 preteral'ily the inner member, is composed otsections or halves which are retained in the intended relation by theseparator for the balls or rolling elements, so as to prevent thedisplacement ot the parts olt the bearing when handling or shipping thesame, before the bearing placed in its mounting; and also to provide abearing which is ot improved eoi'istruction in the other respectshereinafter described and set forth in the claims.

ln the acconipanying d rawinfs:

Figure l is an end elevation of a ball bearing embodying the invention,a port-ion ot one vot the separator plates being broken away to disclosethe balls and the cross members of the separator.

Fig. 2 is a sectional elevation ot the bearing7 indicating by brokenlilies the bearing in position in its n'iountino'.

Fig. 3 is an enlarged fragmentary sectional elevation of the bearing.

' The bearing shown in the drawings comprises an outer race-ring ormember, a divided or sectional inner race-ring or meinber composed o'l'two sections or halves, a circular' series or" balls arranged betweenthe inner and outer race-menibers in grooves or races in said members,and a ball separator by which the balls are spaced at regular intei-valsaround the bearing and which holds Specincation of ietters Patent.

together the halves or sections of the divided raceanember.

10 represents the outer race-ring or ineinber; ll, 1l the sections orhalves of the divided inner race-ring or member and l2 the ballsarranged between the inner and .outer race-meinbers. rlfhe balls areconfined and roll in a ball race orgroove 13 in the inner periphery otthe outer race nien'iber and in a race or groove 14 formed partly ineach et' the two sections or halves ot-the inner race member. The twohalves or sec .tions of the inner 1ace-iiieinber preferably meet orcontact with each other in or substantially in the plane o't the centersofthe series ot balls, and the race contour or curvature ot' eachsection et the inner member is ground with a radins slightly longer thanthe radius of a ball, so that when the parts are assembled into theworking position the center ot the are ot the right hand racepart is alittle to the lett ol the ball center and the center of the arc of thelett hand rare-part is a little to the right oi the ball center`r seeFig. 23. "lhe ell'ect of this is that the balls do not ioll on orcontact with the meeting edges olf the two race-sections or in the jointwhere the.)Y collie together. 'lhere is accordingly no danger olf theinner ring sections breaking down at thejoint.

'.lhe ball separator .shown comprises separate side plates or members 13arranged at opposite sides olfY ythe series olf balls. and eross-pi mesor portions lo which connect the two side plates and pass between theballs forming separate pockets or spaces in which the balls are eonlinedand held in spaced relationship in [he bearing. As shown, the.cross-interes 16 ol` the separator are Jformed by separate bars orplates provided with reduced ends which are riveted in holes in the sideplates ot the separator.

The. inner edges or poi-liens oi the side` plates ol1 the separatoroverlap or extend 'inwardly at the outer sides oli outwardly iacingshoulders or portions 17 on the, two

coming apart While it is being handled or shipped. When the bearing ismountedand in use the tWo halves or sections of the inner ring or memberare held firmly together 1n the mounting between suitable shoulders orparts on the shaft or spindle on Which the bearing is seated. `When thebearing is in or grooves without interrupting the circumferentialcontinuity or' the races or racemembers or rovidincf holes or s )acesfor the introduction of the balls. The bearing is therefore suitable fortaking` heavy thrust loads in both directions. Nevertheless the bearing`can be assembled and handled as a unitary structure before it is placedin its mounting.

I claim as my invention: 4

l. A bearing comprising inner and youter race-members, interposedrolling; elements arranged to roll in races in said race-niembers, oneof said race-members being co1nposed ot separate sections, and aseparator for said rolling elements having' portions which ccperate withportions of said sectional race-member to hold the sections in place.

2. A bearing comprising' inner: and outer race-members interposedrolling elements arranged to roll in races in said race-rnembers, one ofsaid raeeonembers being cornposed of separate sections, each termino` aportion of one of said races, and a separator for said rolling elementshaving portions lwhich overlap portions of said sectional race-member tohold the sections in place.

3. A bearing` comprising' inner and outer race-members, interposed ballsarranged to roll. in ball races in said race-members, one

of said race members and its ball race being divided substantially inthe plane of the center of said balls into separate sections, and aseparator for said balls having portions Which overlap portions of saidsec# tional race-member to hold the sections in place.

4. A bearing comprising;` inner and outer race-members, interposed ballsarranged to roll in ball races in said race-members, said innerrace-member and its ball race being divided substantially in the planeof the centers of' said balls into separate sections, and a separatorfor said balls having portions which overlap portions of said sectionalrace-member to hold the sections in A place.

5. A bearing comprising inner and outer race-members, interposed'ballsarranged to ,roll in ball races in said race-members, one

of said race-members and its ball race bef ing' divided substantially inthe plane of the centers of said balls into separate sections, saidballs contacting with said divided race at a distance 'romthe jointbetween the race sections, and a separator for said balls havingport-ions which overlap portions of said sectional race-member tp holdthe sections in place.

6. A bearingcomprising inner and outer race-members, interposed nrollingelements arranged to roll in races in said race-inembers, one of saidrace-members being` co1nposed of Separate sections each `forming aportion of one of said races, and a separa tor for said rolling elementshaving separate side plates which are connected by cross-piecesextending between the rolling elements and overlap portions of saidsectional race-inember to hold the sections in place.

lgitness my hand this 18th day of June,

FREDERICK lV. GURNEY. `Witnesses:
